What is a ternary blend?

• A. A blend of two different refrigerants.
• B. A blend of three different refrigerants.
• C. A blend of four different refrigerants.
• D. A single refrigerant.

Answer: (B)

A ternary blend is a mixture of three different refrigerants. In refrigeration systems, combining three components lets designers balance properties like pressure, temperature glide, and lubricant compatibility to meet the desired performance. This is why a ternary blend is specifically three refrigerants mixed together. By comparison, a binary blend uses two components, a quaternary blend uses four, and a pure refrigerant is a single component. For example, R-404A is a ternary blend of three refrigerants chosen to achieve suitable low-temperature performance.
